One end of the limiting groove 43 extends to the edge of the connecting plate 4 and forms a plug-in port, and the other end of the limiting groove 43 extends into the connecting plate 4 and forms a stop surface. The limiting protrusion 51 is plugged into and pulled out of the plug-in port in the limiting groove 43 and stops with the stop surface, wherein the limiting protrusion 51 is limitedly matched with the limiting groove 43 to limit the relative movement of the connecting plate 4 and the coal blocking plate 5 except for the plug-in match.

[0025] In this embodiment, the transfer point of the belt conveyor is limited and shielded by the coal blocking plate 5 to avoid the situation of coal leakage in the traditional way. The support and installation of the coal blocking plate 5 are realized by the mounting seat, the mounting frame 3 and the connecting plate 4, which is conducive to the firm installation of the coal blocking plate 5 and the structural strength of the coal blocking device of the belt conveyor, and the reliability and stability of the coal blocking. Further, the connecting plate 4 in this scheme is detachably arranged by the fastening assembly and the coal blocking plate 5 is plugged and unplugged on the connecting plate 4 by the cooperation of the limiting groove 43 and the limiting protrusion 51, which is conducive to the rapid disassembly and assembly of the connecting plate 4 and the coal blocking plate 5, and it is convenient for the operator to replace the damaged coal blocking plate 5 and the connecting plate 4 in the working face environment in time, which is conducive to improving the disassembly and maintenance efficiency of the coal blocking plate 5. At the same time, it is also convenient for the operator to replace the appropriate coal blocking plate 5 and the connecting plate 4 according to the actual situation in the working face environment, which is conducive to improving the applicability of the coal blocking device of the belt conveyor.

[0026] Preferably, the limiting protrusion 51 is a dovetail protrusion with a trapezoidal cross section, and the limiting groove 43 is a dovetail groove. This arrangement is conducive to limiting the relative movement of the connecting plate 4 and the coal baffle plate 5 other than the plug-in fit, avoiding the problems of deviation during installation and the coal baffle plate 5 falling off after installation, and ensuring the supporting effect of the connecting plate 4 on the coal baffle plate 5.

[0027] like Figures 1 to 3 As shown, there are multiple connecting plates 4, and any one of the connecting plates 4 has a limiting groove 43. The coal blocking plate 5 has multiple limiting protrusions 51 corresponding to the multiple limiting grooves 43, and the coal blocking plate 5 is plugged and matched with the multiple connecting plates 4. This arrangement further improves the reliability and stability of the installation of the coal blocking plate 5. Among them, the coal blocking plate 5 in this embodiment is a rectangular plate, and there are two connecting plates 4 in this embodiment, and the coal blocking plate 5 has two corresponding limiting protrusions 51.

[0028] Specifically, the mounting frame 3 is a plate-like structure with a concave cross-section. The mounting frame 3 includes a base plate and two side plates. An installation positioning structure is provided between the base plate and the connecting plate 4. When the base plate and the connecting plate 4 are positioned and installed by the installation positioning structure, the side plate and the connecting plate 4 are detachably connected by a fastening assembly.

[0029] In this embodiment, the connecting plate 4 is first pre-installed in the "concave" area of ​​the mounting frame 3 through the installation positioning structure, and then connected to the mounting frame 3 through the fastening assembly, which is beneficial to ensure the reliability of the installation of the connecting plate 4, and is also beneficial to improving the connection effect and structural strength of the connecting plate 4 and the mounting frame 3.

[0030] like Figure 2 and Figure 3 As shown, the installation positioning structure includes a positioning hole 32 and a positioning column 42, the positioning hole 32 is set on the bottom plate, the positioning column 42 is set on the side of the connecting plate 4 facing the bottom plate, the side plate has a first mounting hole 31, and the connecting plate 4 has a second mounting hole 41. When the positioning column 42 is inserted into the positioning hole 32, the first mounting hole 31 corresponds to the second mounting hole 41, and the fastening assembly passes through the first mounting hole 31 and the second mounting hole 41 and is threadedly connected to the second mounting hole 41. In this embodiment, when the connecting plate 4 needs to be installed, the positioning column 42 of the connecting plate 4 is first inserted into the corresponding positioning hole 32. With the completion of the positioning installation of the connecting plate 4 and the mounting frame 3, the first mounting hole 31 will correspond to the second mounting hole 41. The fastening assembly is a fixing bolt, and the operator allows the fixing bolt to pass through the first mounting hole 31 and be threadedly connected to the corresponding second mounting hole 41, thereby completing the installation of the connecting plate 4. This arrangement is conducive to the rapid disassembly and assembly of the connecting plate 4.

[0031] Preferably, the bottom plate and the connecting plate 4 are positioned and installed by multiple installation positioning structures, and the side plate is connected to the connecting plate 4 by multiple fastening components. In this embodiment, there are three installation positioning structures, and the three installation positioning structures are sequentially arranged at intervals along the height direction of the mounting frame 3 and the connecting plate 4; the side plate in this embodiment is connected to the connecting plate 4 by three fastening components, and multiple groups of first installation holes 31 and second installation holes 41 are also sequentially arranged at intervals along the height direction of the mounting frame 3 and the connecting plate 4.

[0032] like Figure 2 and Figure 3As shown, a plurality of reinforcing ribs 33 are provided on the bottom plate of the mounting frame 3, and the side of the reinforcing ribs 33 facing away from the bottom plate abuts against the coal blocking plate 5. There are three reinforcing ribs 33 in this embodiment, and the three reinforcing ribs 33 are sequentially arranged at intervals along the height direction of the mounting frame 3, and each reinforcing rib 33 abuts against the side of the coal blocking plate 5 facing the mounting frame 3. This arrangement avoids a situation where there is a large spacing area between the middle part of the coal blocking plate 5 and the mounting frame 3, and when the coal blocking plate 5 is hit, the area of ​​the coal blocking plate 5 corresponding to this part is easily damaged. The rigid support of the coal blocking plate 5 by the plurality of reinforcing ribs 33 improves the coal blocking effect of the coal blocking plate 5, which is conducive to prolonging the service life of the coal blocking plate 5.

[0033] Preferably, a gasket is laid on the inner wall of the limiting groove 43 to increase the friction between the limiting protrusion 51 and the limiting groove 43, thereby preventing the coal blocking plate 5 from sliding and moving on its own, and improving the tightness of the connection between the coal blocking plate 5 and the connecting plate 4.

[0034] Furthermore, the mounting seat includes a mounting plate 1 mounted on the working surface and a plurality of fixing columns 2, the plurality of fixing columns 2 are spaced apart along the circumference of the mounting plate 1, and the connecting plate 4 is connected to a side of the plurality of fixing columns 2 away from the mounting plate 1. There are four fixing columns 2 in this embodiment, and the four fixing columns 2 are respectively mounted at the four corners of the same side of the mounting plate 1.

[0035] Preferably, the coal blocking plate 5 is made of alloy steel, which is beneficial to ensuring the coal blocking effect of the coal blocking plate 5 and extending the service life of the coal blocking plate 5.

[0036] To sum up, the utility model provides a coal blocking device for a belt conveyor, the principles of which include: when installing the connecting plate 4, first, the positioning column 42 is plugged into the positioning hole 32, and then the fastening assembly (fixing bolt) is installed at the first mounting hole 31 and the second mounting hole 41, so as to facilitate the quick installation and connection between the connecting plate 4 and the mounting frame 3; then, when installing the coal blocking plate 5, the limiting protrusion 51 and the limiting groove 43 are used to facilitate the quick replacement of the damaged coal blocking plate 5 in the working surface environment, thereby improving the maintenance efficiency of the coal blocking plate 5.
